GETTING STRTED We strongly recommend that the Noby-420 is first powered up with all 4K7 End Of Line resistors fitted at the panel as supplied by the factory. In this way you can gain confidence that the panel is operating correctly before introducing detector and sounder circuits. Power-Up With Battery Connect two 12v SL batteries in series (+ ve to ve) to form a 24 volt battery stack, using the battery jumper link supplied. Connect the black battery lead to the battery stack ve terminal. Connect the red battery lead to the battery stack + ve terminal. It is normal to see a small spark. The Common Fault LED will be continuously lit together with flashing PSU and CPU fault LEDs. These faults are also accompanied by an audible fault tone signified by 4 rapid pips every 4 seconds. Press [3][6][3][6] [1][4][5] to silence and perform a System Reset observe a 3 second LED test. The panel should then settle to quiescent state with all LEDs off. Connect the mains power supply to the fused screw terminal block The panel should now be in a standby state with only the green Power LED continuosly lit. Power-Up With Mains Connect the mains power supply to the fused screw terminal block. The green Power LED will be continuously lit. The Common Fault LED will be continuously lit together with flashing PSU and CPU fault LEDs. These faults are also accompanied by an audible fault tone signified by 4 rapid pips every 4 seconds. Connect two 12v SL batteries in series (+ ve to ve) to form a 24 volt battery stack, using the battery jumper link supplied. Connect the black battery lead to the battery stack ve terminal. Connect the red battery lead to the battery stack + ve terminal. It is normal to see a small spark. Press [3][6][3][6] [1][4][5] to silence and perform a System Reset observe 3 second LED test. The panel should now be in a standby state with only the green Power LED continuously lit. Notes 1. The panel will persist in reporting a PSU fault after a System Reset if the battery is either not present or the battery fuse F4 has blown. 2. Whilst there is a measure of protection against accidental reverse connection of the battery, such action will blow fuse F4 and may cause permanent damage to the panel. Noby-420 Installation & Programming Instructions Rev3 Page 2 of 12
Power Supply Unit The Noby-420 has a 27volt regulated PSU, with a continuous current rating of 1.0, and a 20 minute rating of 1.5. The PSU is designed to meet the internal standby power requirements of the Noby-420 and also to charge and maintain the SL standby battery in optimum condition. The battery standby time is dependant upon the overall system current drawn, including any ancillary equipment connected to the ux 24v. lso it is strongly recommended that the continuous system standby current does not exceed 1.0, because some reserve PSU current may at times be required to rapidly re-charge the battery (e.g. after an alarm condition or prolonged period of mains loss). The Noby-420 enclosure can accommodate two 12v/7hr SLs connected in series. Care must be taken when planning an installation that there is sufficient battery capacity to meet the relevant standards regarding battery standby times. lways ensure that the maximum current drawn in alarm does not exceed the 3.0 battery fuse limit (F4). The PSU is monitored for : i) Mains bsence Power LED extinguishes when mains absent for more than 90 seconds and flashes once mains restored. Mains absence is accompanied by an intermittent warning bleep every 16s (mutable). ii) Low Voltage < 21v PSU Fault LED continuously lit whilst voltage < 21v and flashes when the voltage is restored to > 23v iv) Battery Capacity Test PSU Fault LED flashes iii) Fuse F4 (Battery/Low Volts) PSU Fault LED flashes v) Fuse F1 (ux 24v) PSU Fault LED flashes Note 1: PSU faults are accompanied by a fault tone signified by 4 rapid pips every 4 seconds. Note 2: The Battery Capacity Test is performed immediately after a System Reset and thereafter at 12 hour intervals. Noby-420 Installation & Programming Instructions Rev3 Page 3 of 12
Inputs Zone Detector Circuits The Noby-420 requires that each detector zone is terminated with a 4K7 End Of Line resistor. This EOL resistor is necessary to facilitate open circuit, short circuit and head removal monitoring. The total current drawn by the detectors on each circuit must not exceed 2m, which means that 20 detectors can be connected to each zone (based on a typical 100u maximum per detector). Similarly, if the detectors are specified at 50u maximum current draw, then 40 detectors per zone can be connected. Class Change Input (Direct Bell Ring) positive going input signal to activate on the sounders directly (subject to their isolation status). The input is non-latching and no indication is given on the display. Fault Input n input signal permitting the fault status of remotely connected ancillary equipment (eg. a communication device) to be indicated on the Noby-420 display panel, causing the Common Fault LED to flash. The polarity of the Fault Input signal is programmable see Engineer Programming. Outputs Sounder Circuits Conventional 4K7 End Of Line resistor monitoring requiring polarised bells or sounders with a combined output current of 1.25 across the 2 sounder ports. Each sounder circuit is individually fused and monitored. Fire Relay Output Double pole voltage free contacts, each rated at 1@30V, activated upon detection of a zone fire or by the keypad operated Evacuate function. It is latched until a System Reset. The relay can be isolated - see User Keypad Functions / Isolation. The Fire Relay Output is not triggered by the Class Change (Bell Ring) Input or from any activation of a zone that has been programmed as a non-latching zone. The Fire Relay contacts are NOT mains voltage rated, and any mains voltage switching MUST be done with the addition of a mains rated slave relay. Panel Sounder (Piezo) n on-board piezo sounder provides the panel s internal fire and fault warning tones. Fire tone = continuous rapid pips. Fault tone = 4 rapid pips every 4 secs. Warning Tone = 2 pips every 16 secs. ux 24v 27.3v (nominal 24v) auxiliary supply fused at 1 (Fuse F1), monitored. Fault Output Signals real-time status of System Faults from all sources (zone faults, sounder circuit faults, PSU etc.). It is an open collector PNP output normally driven to 24 volts, and dropping to 0 volts during a fault condition. The output has a 470 ohm series limiting resistor.

Noby-420 Installation & Programming Instructions Rev3 Page 7 of 12
Zone Faults Zone Fault LED continuously illuminated Disconnect the relevant zone and replace with the EOL resistor (4K7) at the zone terminal. If the fault can now be cleared then there is a possible wiring error in the zone. Check that the correct value EOL resistor is fitted at the end of the zone. Check that the wiring and connections at each detector are consistent, and not crossed-over at any point along the cable run. Check that all manual call-points in the zone are intact and fitted with an appropriate series resistor, typically 470 ohms. If a Zone Fault LED becomes continuously illuminated when a head is removed, then that detector base may be the wrong type. Check that a schottky diode is fitted and correctly connected. Replace the suspect detector base if necessary. Zone Fault LEDs Flashing One or more zones are isolated. Zone Fault LED intermittently winking detector head is either missing or incorrectly connected. Check all detector heads on the corresponding zone are fully seated in their bases. Some (older) detectors may be incompatible with head-removal monitoring in which case it is recommended to set the Head Removal Monitor Inhibit (System Options 2). Fire is detected as Zone Fault Check all detector heads on the corresponding zone are fully seated in their bases. The panel monitors the zone for a short circuit. Some (older) detectors and call points may be incompatible with short circuit monitoring in which case it is recommended to set the Zone S/C Inhibit (System Options 2). Sounder Faults Sounder Fault LED continuously illuminated Enter the code [6][2][5][3][1][1] to bring up the sounder fault display, shown by the zone fault LEDs. Check the corresponding sounder fuses F2 and/or F3. Disconnect the suspect sounder circuit and fit a 4K7 EOL resistor at the sounder terminal. If the sounder fault clears then there is a possible wiring fault in the circuit. Check all connections between sounders. Check that the correct value 4K7 EOL resistor is fitted in the circuit. Some types of sounders may be incompatible with the Noby-420 sounder circuit monitoring function in which case it is recommended to set the Sounder Circuit Fault Monitor Inhibit (System Options 2). CPU Fault Indication CPU Fault LED Flashing It is normal to see a CPU Fault at power-up, and can be cleared by performing a panel reset. Persistent CPU faults may indicate interference from electrical machinery or RF transmitters in the immediate locality. Common Fault Indication Common Fault LED Flashing persistently Check that the Fault Input polarity is correctly programmed (Engineer Programming Sysop1), and that the Fault_Input terminal, if used, is in the required state to hold-off the Common Fault LED. Note that the Fault_Input Polarity option should be disabled (factory default) if the Fault Input terminal is unused or not connected to remote equipment. larm Relay larm relay not working Check that the relay is not isolated. User Keypad Operation Reset command [3][6][3][6] [5] is ignored nothing happens. Both the external sounders and internal panel piezo sounder must first be muted before the reset button is acknowledged. This can be performed in one operation by performing a Quick Reset [3][6][3][6] [1][4][5]. Noby-420 Installation & Programming Instructions Rev3 Page 8 of 12
